Add-on Option to not include signature when posting

[webbouk]

Is it possible to have a checkbox where a member can choose not to include their signature within a specific post?

Some posts might be of a sensitive nature and the poster might wish not to include their signature as it might be inappropriate or not pertinent to the post they are making.
It would be a good idea if members can select whether or not their signature is included in the post that they are making
